I can't see my podcast on Banshee

I can't see my podcast on banshee after upgrade ubuntu.
Banshee 2.2.
I instaled all codecs.
My mp3 works.
When i call the banshee in term [sudo banshee]. I can see the videos(mp4). But I can't with my user.
(HowTos)

I had to reload my sound drivers because ubuntu had stopped recognizing my sound drivers and I got sound back except from banshee. I have played videos and those worked fine. Everything else seems to have sound. I checked the volume within banshee and it was all the way up. I tried upgrading banshee and it the highest upgrade. I tried downgrading banshee and same thing no sound.
